Impact of the automatic rounding-off function of the computerized physician order entry system on the ordering time and dose dispersion of chemotherapeutic drugs in regimens for hematologic malignancies.

Introduction: EGMAIN-GX is the computerized physician order entry system used in Japan. The automatic rounding-off of the calculated dose of chemotherapeutic drugs is an update in version 4, compared to version 2. We conducted a comparative study between EGMAIN-GX versions 2 and 4 to estimate the effect of the automatic rounding-off function on ordering time and dose dispersion.

Nuclear and chloroplast microsatellite analysis of Abies sachalinensis regeneration on fallen logs in a subboreal forest in Hokkaido, Japan.

Fallen logs are the main regeneration sites for Abies sachalinensis (Sachalin fir) in subboreal forests in Japan. We surveyed the spatial genetic structure of different demographic stages in a 4.29-ha natural population of A.

Prediction of the ablated area by the spread of microbubbles during radiofrequency ablation of hepatocellular carcinoma.

Background/aim: Radiofrequency ablation (RFA) is effective for the treatment of hepatocellular carcinoma (HCC). To prevent the ablation of adjacent organs and vessels, the spread of microbubbles generated by heating during RFA was observed by ultrasonography (US) and used to predict the ablated area; however, several reports documented that discrepancies existed between the spread of microbubbles and the ablated area.

Patients And Methods: The spread of microbubbles during RFA was observed by US in 24 patients with HCC and the areas were compared with the defect of enhancement in contrast enhanced (CE)-US, using Levovist in the same plane.
